Abstract

LA INVENCION SE REFIERE A UN PROCESO DE ESTIMACION DE DISPARIDAD ENTRE LAS IMAGENES QUE CONSTITUYEN UNA IMAGEN ESTEREOSCOPICA. EL PROCESO CONSISTE: EN UNA PRIMERA ETAPA, EN REALIZAR UNA MISMA DESCOMPOSICION JERARQUICA DE CADA IMAGEN (ID(T), IG(T) MONOSCOPICA, POR NIVELES DE RESOLUCION, CONSTITUYENDO AL MENOS TRES PIRAMIDES DE IMAGENES DE RESOLUCIONES CRECIENTES, UNA PIRAMIDE DE IMAGENES DE BAJA FRECUENCIA Y DOS PIRAMIDES DE IMAGENES DE LATA FRECUENCIA SEGUN LAS DIRECCIONES HORIZONTAL Y VERTICAL DE LA IMAGENES; EN UNA SEGUNDA ETAPA, EN ESTIMAR UNA DISPARIDAD (D) AL NIVEL DE RESOLUCION MAS BASTO Y EN AFINAR LA ESTIMACION EN CADA NIVEL A MEDIDA QUE LA RESOLUCION AUMENTA. APLICACION: TRATAMIENTO DE EFECTOS ESPECIALES DE IMAGENES ESTEREOSCOPICAS.
